The Gen 4 Grip Force Adapter was specifically developed to fit Glock's Gen4 pistol in its base "short frame" configuration. The short frame configuration does not utilize either the Medium or Large factory grip panel on the frame. The Gen 4 Grip Force Adapter eliminates the drawbacks associated with permanent modifications to your factory pistol. The Gen 4 Grip Force Adapter mates completely to the back strap of the Gen 4 frame, permitting the shooter's hand to conform to the frame in a more secure manner. This offers more control and allows the shooter to index the pistol on target more efficiently.
